Oleaginous microalgae are considered to be a potential major biofuel producer in the future
since, under conditions of nitrogen deprivation, they are capable of containing high amounts …

<? xm-replace_text {Heading}?> Abstract Mathematical modeling is becoming ever more
important to assess the potential, guide the design, and enable the efficient operation and …

The goal of this technical note is to design interval observers for a class of nonlinear
continuous-time systems. The first part of this work shows that it is usually possible to design …

In this paper we design an interval observer for the estimation of unmeasured variables of
uncertain bioreactors. The observer is based on a bounded error observer, as proposed in …

We propose nonlinear observers for a class of biotechnological processes. These observers
are an extension of the open loop asymptotic observers (observers with unknown inputs) …

It is well documented that the combination of low nitrogen and phosphorus resources can
lead to situations where colimitation of phytoplankton growth arises, yet the underlying …

In an interesting paper R. Rajamani and YM Cho have proposed a systematic methodology
to design observers. They have introduced a new problem: relation between distance to …

Based on intervals bounding the uncertain initial conditions, inputs, model parameters and
measurements, interval observers provide guaranteed intervals for the state trajectory …

In this paper we develop and apply a robust interval observer to estimate the unknown
variables of uncertain chaotic systems. We consider that bounds of the uncertainties are …

In this study, a low-cost RGB sensor is developed to measure online the microalgae
concentration within a photo-bioreactor. Two commercially available devices, ie, a …
